China’s Ministry of Agriculture and Rural Affairs (MARA) has formally given Calysta’s single cell protein full approval for use in fish and shrimp feeds after an extensive evaluation process.

FeedKind is produced by fermentation for aquaculture feeds and pet foods. The company has stated that they have validated the product with extensive trials across high interest aquaculture species, including shrimp, seabass and salmon.

Research previously demonstrated distinct benefits of using FeedKind in shrimp diets, concluding that it promotes strong, healthy growth, while also helping activate shrimps' immune response to Vibrio, the causative agent of early mortality syndrome (EMS).

Calysta* has teamed up with Adisseo to form a joint venture - called Calysseo - to produce FeedKind in China. Calysseo’s first production plant has been built in Chongqing and is already operational. The company claims that naturally-occurring microbes that use methane are used in the production process for FeedKind, helping it to be a more sustainable product.

Herman Hong, Adisseo aquaculture manager for China, stated in a press release: “This is a significant step forward for the adoption and use of fermented proteins across global food systems. MARA approval is more than simply a regulatory step, it is validation that our product is a healthy and practical ingredient for use in aquaculture systems and opens the door for the Chinese aquaculture sector to set new standards in sustainable feed practices.”

Sun Bin, Calysseo’s chairman, added: “This is an important step forward not just in helping make food production systems more sustainable, but in improving global food security, by providing feed producers with a domestically-produced, reliable feed ingredient that isn’t susceptible to weather or climate-driven fluctuations in supply.”
